Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing financial data sharing methods lack adequate security measures to prevent unauthorized access and leakage of confidential financial data, especially for unlisted enterprises, necessitating a secure sharing solution that ensures data integrity and accessibility only to authorized users.
Innovation Solution
A financial data secure sharing method utilizing a cloud server that involves user identity authentication through dual-factor authentication, unified format conversion, blockchain-based encryption, and ordered set storage, ensuring secure data sharing and accessibility based on user identity authorities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If financial data is shared among relevant personnel, then data accessibility is improved, but data security deteriorates due to potential unauthorized access and leakage
Solution Approach 1:
The patent segments data access authority by user identity levels, dividing the data sharing system into hierarchical access tiers. Different users receive different levels of access permissions based on their identity, allowing broad accessibility while maintaining security through controlled segmentation of access rights.
Solution Approach 2:
The patent introduces blockchain technology as an intermediary layer between data storage and access. The blockchain provides cryptographic verification and smart contract-based access control, acting as a trusted mediator that enables secure data sharing without requiring direct trust between data providers and users.
2Reliability
If encryption methods are applied to financial data, then data security is improved, but authentication speed deteriorates due to additional processing time
Solution Approach 1:
The patent performs preliminary format unification and preprocessing of financial data before encryption. By standardizing data formats in advance and organizing them according to preset storage structures, the system reduces the complexity of subsequent encryption operations, thereby maintaining security while improving authentication speed.
3Productivity
If unified format conversion is performed on financial data, then data storage efficiency is improved, but data processing time deteriorates
Solution Approach 1:
The patent changes the data format parameters to a standardized structure that optimizes both storage efficiency and retrieval speed. By transforming financial data into a unified format with consistent schemas and metadata structures, the system achieves compact storage while enabling efficient querying and processing through the standardized parameters.

AI summary
A financial data secure sharing method, a device and a system based on a cloud server include steps of: logging-in with a terminal through a data access sharing interface provided by the cloud server to obtain a financial data sharing authority for a financial data sharing party; filling-in and uploading financial data according to a data sharing upload format provided by the cloud server; performing a unified format conversion on the financial data, so as to generate unified-format financial data; selecting an encryption method for the unified-format financial data; processing the unified-format financial data with encryption authentication, and obtaining an encryption authentication result; and storing the encryption authentication result in a memory of the cloud server based on a preset storage structure, and providing data sharing to a corresponding user through the data access sharing interface. The financial data can be shared according to the user identity authority.
